Paste a YouTube link into YTmp3, choose 1080p, and the video downloads as an MP4 with sound. It is free, needs no account and no software, and works the same on Android, iPhone and desktop. A typical four-minute video at 1080p comes to around 60–90 MB.
1080p Full HD is 1920×1080 pixels — the resolution most people actually want. It is sharp on a phone, sharp on a laptop, and still sharp on a television, without the file sizes that come with 4K.
The whole thing takes a few seconds. There is no queue and no sign-up, and no download cap is applied on this side.
Because YouTube does not store 1080p as a single file. Above 720p it keeps the picture and the sound as two separate streams, and they have to be joined back together before you get a playable video.
That joining is why a 1080p conversion takes a few seconds longer than a 360p one, and skipping it is why some tools hand you a 1080p file with no audio at all. To be precise about who does what: the joining is performed by the conversion service your link is passed to, not on this site. When a silent file does turn up, retrying the conversion or stepping down to 720p — where the audio is already inside the single file — is the fix.
Size depends on the length of the video and how much motion it contains. A static talking-head video compresses far better than a music video or a game clip. As a rough guide, for a four-minute video:
| Resolution | Pixels | Rough size (4 min) | Best for |
|---|---|---|---|
| 360p | 640×360 | ~12 MB | Slow connections, saving data |
| 480p | 854×480 | ~20 MB | Phone screens |
| 720p HD | 1280×720 | ~40 MB | Everyday viewing |
| 1080p Full HD | 1920×1080 | ~60–90 MB | Laptops, TVs, keeping |
| 1440p (2K) | 2560×1440 | ~150 MB | Large monitors |
| 4K Ultra HD | 3840×2160 | ~400 MB | Big screens, editing |
For most people 1080p is the sweet spot. Going up to 4K multiplies the file size roughly five times, and on a phone screen you will not see the difference.
Because the creator never uploaded it at that quality. YTmp3 can only offer the resolutions YouTube actually holds for that video. If it was published in 720p, no tool anywhere can give you a real 1080p copy — anything claiming to has simply stretched the picture, which makes the file bigger and slightly blurrier, not better.
Older videos, small channels and some live recordings are commonly capped below 1080p. If 1080p is not in the list, 720p is the next best real option.
The sound inside the MP4 is the audio track YouTube stores with that video, normally around 128kbps AAC. That is the same audio you hear when streaming — nothing is lost in the download.
If you only want the sound and not the picture, use the MP3 or M4A option instead. MP3 comes out at up to 320kbps depending on the source, and M4A is the original stream copied without re-encoding.
Yes. YTmp3 runs in the browser, so nothing needs installing on Android or iPhone.
Use Wi-Fi for 1080p if you can. A handful of videos at that size will make a noticeable dent in a mobile data allowance.
Shorts yes, playlists no. Paste a Shorts URL and it downloads at whatever resolution it was uploaded in — many Shorts are 1080p vertical, and there is no watermark on YouTube Shorts for anything to remove. A playlist URL returns an error: the converter takes one video ID at a time, so a playlist has to be worked through video by video.
